was offered this little fish to my daughter when she was only a few months she is now 3 and a half years, and she always plays with! the songs are certainly a little soulantes for us adults, but the kids love, and my other daughter 8mois already appreciated! While the little fish is quite heavy and therefore tends to sink, but you always hear his songs, even under water! very good resistance to immersion, and I've never changed the batteries, however, it plays a lot with! I recommend.
